Fallout: Equestria is a crossover fan-fiction between the My Little Pony: Friendship is Magic television series and the Fallout video game series, and was written by Kkat. First published in April 2011 and completed on Christmas of that year, Fallout: Equestria spans 45 chapters (as well as a prologue, introduction, epilogue, and afterword), and contains over 620,000 words, making Fallout: Equestria one of the longest self-published works of derivative fiction in existence.
It has become one of the most critically well-received derivative works in the My Little Pony: Friendship is Magic community, and has a substantial cult following that has produced thousands of new works of art, literature, and music dedicated to the fan series.
